Trek Superfly 8 — Review
As my first post, I’m going to review my current bike, a Trek Superfly 8 2015 model. As a side note, I’ll be starting an upgrade project with this bike soon, you can find it here.
Trek Superfly 8 Specs and pricing
Back in 2015, a brand new Trek Superfly 8 would set you back around 1,500€ depending on where you bought it. For that price, you would get an aluminum frame with Trek’s G2 geometry paired with a FOX Float 32 CTD Performance suspension fork. Stock tires were Bontrager XR1 Experts which were mounted on Bontrager Mustang Elite Tubeless Ready wheels with through axles both front and rear (15 x 100 mm, 142 x 12 mm). The drivetrain consisted of mainly Shimano SLX 2 x 10-speed groupset with a Shimano XT rear derailleur. The brakes were also Shimano SLX paired with Shimano SLX rotors (180 mm front, 160 mm rear). Handlebar, stem, seat post, and saddle were all made by Bontrager. You can check out the exact specs here.
On the trail
Weighing in at around 11,6 kg the Superfly 8 is not the lightest Cross Country bike out there, but not the heaviest either. Fox float 32 fork with 100 mm of suspension travels does a good job at soaking up the bumps. Large 29″ wheels make sure the bike rolls over obstacles well. The frame is both flexible yet stiff enough for good power transfer. Compared to cheaper mountain bikes with 26″ wheels, the ride is surprisingly comfortable thanks to its larger wheels and a good frame. The 2 x 10-speed drivetrain offers enough gear range for any situation and despite being made of Shimano’s lower end components shifting is quick and crisp. Shimano’s SLX brakes are considered one of the best budget brakes out there. They certainly work well with no complaints whatsoever.
The only real complaint comes from the stock wheelset which is quite heavy at almost 2,2 kg. The weight definitely makes the bike feel a bit sluggish and heavy. Despite that the bike wheels great on flat sections and uphills, but it can also handle downhills with confidence. It’s not a trail bike, but a solid all-around Cross Country bike.
Trek Superfly 8 is a solid performer with a Cross Country focus. To make it even better my recommendation is to upgrade to a lighter wheelset.
- Good aluminum frame paired with a decent fork
- Shimano’s SLX groupset is a solid performer, especially the brakes
- Through axles both front and rear
- Stock wheelset is very heavy at just under 2,2 kg
- A bit expensive for the kit, but often great value if you can find it second hand.
